IMPROVEMENT IN MILK-CO OL ERS.

Specification forming part of Letters Patent No. 165,364, dated July 6,1875; application filed January 28, 1875.

To all whom it may concern Be it known that we, EDWARD N. PORTER andMELVILLE B. EATON, of Morrisville, in the county of Lamoille, and in theState of Vermont, have invented certain new and useful Improvements inMilk-Coolers; and do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings and to the letters of reference marked thereon, making a partof this specification.

The nature of our invention consists in a device for regulating theheight of the water in milk-coolers, and also in the construction of thecooler, as will he hereinafter more fully set forth.

In the annexed drawing, Figure 1 is a perspective view of a milk-coolerembodying our invention. Fig. 2 is a detailed view of apart thereof.

A represents an ordinary milk-cooler, with tortuous perforated pipe Bplaced in the bottom thereof, for the admission of water, which passesinto the end a of said pipe. The other end of the perforated pipe B isinserted in a short tube, 12, fastened-in and passing through the sideof the cooler. This end of the pipe is closed from the outside by aplug, d. If the pipe B should become dirty, or the perforations beclogged, water is allowed to accu- Inulate-in the cooler till the pipeis perfectly covered, when the plug cl is taken out, and the water fromthe pipe will pass out through this end. The back suction of the waterfrom the cooler into the pipe will soon clear the holes, and the pipewill also soon become free of dirt; the plug d is then inserted again.On the side of the cooler Ais formed a pocket, 0, in which the waterstands the same height as in the cooler. In this pocket is theoutletpipe e, having a flexible pipe, f, attached to its inner end. Thispipe is supported by a chain, h, in such a manner as to hold its inneror free end at any desired elevation, and thereby regulating the heightof the water in the cooler with a single outlet. 7

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. An adjustable flexible pipe attached to the inner end of theoutlet-pipe of a milkcooler, for regulating the height of the water inthe cooler, as herein set forth.

2. The combination, with the milk-cooler A, tortuous perforated pipe B,having short tube 1), and upward-bent pipe a, of the pocket 0,outlet-pipe e, flexible pipef, and chain or cord h, all constructedsubstantially as set forth.

In testimony that We claim the foregoing, we have hereunto set our handsthis 12th day of December, 1874.
